REVERSIBLE PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 660,734. dated October 30, 1900.

Application filed January 22, 1900- Serial No. 2,372. 1 model-1 To all whom, it may concern: I

Be it known that we, ROBERT J. NORTHAM, with residence and post-office address at the city of Los Angeles, and ANDREW J. BRAM- LETTE, with residence and post-office address at Downey, county of Los Angeles, State of California, have invented certain new and useful Improvements in Reversible Pipe Tongs and Wrenches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to improvements in a combined reversible pipe tongs and wrench; and our invention consists in certain features of novelty hereinafter described and claimed.

Figure 1 represents a side elevation of our improved tongs and wrench, showing the device applied to a pipe. Fig. II is a detail View showing one of the jaws removed. Fig. III is a perspective of one of the jaws. Fig. IV is a perspective of one of the retaininglugs. Fig. V is a detail perspective of the chain. Fig. V1 is an edge view.

Referring to the drawings, 1 represents ahandle or lever, to the inner end of which are secured double-faced jaws 2. The jaws are preferably made diamond shape, having a series of teeth 3 on each face of the diamond. The jaws are provided with a central bolthole 4 and end holes 5.

6 represents a central bolt, and 7 an end bolt, which pass through the bolt-holes 4: and through the lever 1 at 8 9, thus securing the jaws 2 to the inner end of the lever. The jaws 2 are reversible on the lever, and as each of the four faces 10 is provided with teeth 3 it will be seen that the Wrench will operate the same whichever end of the jaws is presented outwardly and whichever side of the wrench is applied to the pipe or other device that is to be turned, thus enabling the operator to renew the wrench simply by changing the jaws of the lever. The jaws are also provided at their ends with auxiliary jaws ll 12 of an alligator-wrench, which may be used on occasions in which said peculiar form of wrench is specially adapted.

13 represents a slot in the inner end of the lever, into which extends one end of a link 14. of a chain 15, said link having an aperture or hole 16, through which extends the bolt 6, thus securing the chain 15 to the lever 1.

17 represents anchor-shaped lugs on a re versible lug-plate 18. The lug-plate 18 is provided with a slot 19 near the forward end of the plate and with holes 20 near the rear end of the plate. The lug-plates are secured between the jaws 2 and the lever 1 by means of the bolts 6 7, passing through the slot 19 and holes 20, thus clamping the jaws, the lugs, and the levertogether. The object in forming the slot 19 and the multiplicity of holes in the lug-plate is to adjust the tongs in order to accommodate them to two different-sized articles or pipes. The chain 15 is provided with pins 21, extending on each side of the links, said pins engaging the lugs 17 when the chain has been passed around a pipe, such as shown at 22, (see Fig. I,) and as the lugs extend on each side of the lugpiate the chain can be passed around the pipe in either direction and the pins engaged by the lugs. If the chain should not be exactly the right length for efficient work on any particular size of pipe, then the lug-plate may be changed to compensate for the same.

By having the lugs on a separate lug-plate and avoiding placingthem upon the jaws we prevent the discarding of the jaws if the lug should become broken, and vice versa.

We claim as our invention-- 1. In a device of the kind described the combination of a lever, a chain, having projecting pins, reversible jaws and reversible lug-plates intermediate of the lever and the jaws; substantially as set forth.

2. In a device of the kind described the combination of a lever, a chain, reversible jaws having auxiliary alligator-jaws, and reversible lug-plates intermediate'of the lever and jaws; substantially as set forth.

3. In a device of the kind described the combination of a lever having jaws, a chain, and reversible anchor shaped lug-plates; substantially as set forth.

4. In a device of the kind described, the

Combination of a lever, a chain, lug-plates of the auxiliary alligator-jaws, substantially having lugs thereon with a slot and holes in as set forth. said lug-plate for adjusting the same and jaws for engaging the article to be turned,

substantially as set forth.
